“He spoke with [Simpson’s mom] Tina about his concerns and warned that if Ashlee doesn’t get a grip and calm down the partying he won’t hesitate to get a temporary full custody order in place for Bronx,” alleges the supposed snitch.

The blog’s “source” goes on to insist, “With the situation as it is, if Ashlee doesn’t sort herself out soon, Pete believes he will have no option but to go to the courts to get this matter resolved.”

Enough.

As Gossip Cop already reported, there are NO issues between Wentz and Simpson.

The Fall Out Boy bassist is currently on tour, and the notion that he’d suddenly go to court for “full custody” is patently false.

Wentz’s team remains adamant that “Ashlee and Pete are working together to co-parent.”

Nothing has changed — including RadarOnline wrongly adhering to an inaccurate premise.
